The present invention, while applicable in whole or in partto otheruses, is designed more particularly :to provide an improved press forkitchen garbage and like material. 7

It has heretofore been customary to throw kitchen garbage, ashes, bones,and similar refuse, as fast asit accumulates, indiscriminately intoacommon receptacle located in case may be, to await the coming of thegarbage collector- Much of the garbage, if not decayed, soured or mixedwithbones, cans, etc., would have value for feeding pigs, poultry, etc.,but when left to stand in the usual way, itsmoi'sture causesfermentation and decay, flies breed, germs multiply, and

stenches and disease result. Thecollection.

of such filthy stuff is'a nuisance, attended with smells and dust, andrequiring a large force of men and wagons, a dumping ground,etc. i

The object of my present lIlVGIltlOl'h is to provide an improvedapparatus that may be conveniently located in the kitchen or in likeaccessible position, whereby the useful portions of the garbage may bemmejdlately separated from the useless and refuse por-.

tions, whereby the moisture may bepressed out .ofthe garbage, therebyreducing to a very material extent the volume of the stuff to becollected, and whereby the compressed garbage can be convenientlyretained as it accumulates until the collector arrives to remove it.

To this end,my invention consists in the novel apparatus hereinafterdescribed, illustrated 1n-the accompanying drawings and particularlypointed out in the claims at the end of this specification.

While shall describe in the following specification what I regard as thepreferred embodiment of my invention, I wish itdis tlnctly understoodthat the details of the invention may be varied within-wide limitswithout'departing from its scope, and that features of the invention maybe employed withoutits adoption as an entirety.

As illustrated in the accompanying drawings, my invention is shown ascomprising a base Athat may consist of bars'having downwardly bent legs0, these bars being conveniently bolted together, as by across plate 10;Upon the base A, will rest the cans or receptacles B and B, adapted toreceive, respectively, the useful andthe use- I less o'r'refuse garbagethat is to say, one

of these cans will receive. the garbage that is suitable for use as foodfor pigs, poultry, or the like, while the other can B will receive thegarbage or refuse thatis not adapted for such'food purposes. Each of thecans B and B is shown as provided, adja-,

cent its top, with a handle 1), whereby it may be conveniently moved.

From the base A rises the front andtrea r' standards 11 and 12 that areconnected at their top by across bar 13. Between these standards '11 and12, and conveniently bolted thereto as at c, is secured a horizontally,

disposed frame C, preferably of sheet metal. The lower portion of thisframe isformed I as a pan G, into which will flow the liquid thatislextracted from the garbage, and from the bottom of the pan G theliquid will be conducted away by a pipe C to the sewer, drain pipe, orto a pan 15 (see Fig. 4) set beneath the standv A. Within the pan Careformed several openings 20, 21 and 22. theseopenings being surroundedby flanges which risefrom the'bottom of the pan C.

Projecting" forwardly from the walls of; the frame C are the flanges orrails 23 and 2d: that ,may be formed integral with the body,

ofthe frame, as clearly shown in Fig: 3

of the' drawing. These flanges or rails 23 E and E are preferably formedof sheet and 24 serve as supports for the press cans or receptacles Dand D. Preferably, these press cans or receptacles D and D are formed ofsheet metal and at their, bottoms they are provided with outwardlyturned flanges 25 and 26 adapted to rest upon the formed longitudinalslots through which pass the slide plates E and E, each of these 7plates being adapted to be shifted by'its perforated front end 6 intoposition beneath its respective cam D or D". The slide plates metal andthese slide plates rest upon, the flanges that surround the openings 20and 21 formed through the pan C. Preferably, the upper edges of theseflanges 20* and 21 .are formed with outwardly turned edges or flanges 27that will be engaged by downwardly turned flanges 0 (see Fig. 2) formed7 on the under side of the slide plates E and E. To the-bottom of eachof the slide plates E and E are attached depending stops '0 that serveto limit the inward movement of the slide platesby contacting with thefront of the frame C. Upon theupper surface of each of the slide platesE and E (these plates being duplicates one of the other) are flanges fon the under side of the reticulated mounted the guide flanges e (seeFig.v 5) adapted to engage the downwardly turned or'openwork diaphragmsF, one of which 1 extends beneath each of the press cans D, D.

If desired, a vertical flange'e maybe provided adjacent the front ofeach of the side plates E and E. i

The press cans flanges 23 and 24: in position normally above thecorresponding openings 20 and 21 in the pan C and when in such position,the bottoms of these press cans are normally closed by the diaphragms F.These press cans, when in normal position, are above the correspondingcans or receptacles B and B. WVhen in the position shown in Figs. 1 and2 of the drawings, the press cans D and D are interlocked with theirrespective diaphragms F'bythe engagement of themwardly turnedfl'anges'cl at the bottom of the presscans with the edges'of diaphragmsF, as clearly shown in Fig. 2; so'that when the press cans are shiftedlaterally above the press, as will presently be described, the

diaphragms F will be carried with the press When, however, the presscans are cans.

D and D rest upon the returned to normal position above their respectiveopenings 20 and 21, the diaphragms F being interlocked with the flangese on the slide plates E and E, the withdrawal of the slide platesthrough the openings in the front of the frame C will withdraw thediaphragms from beneath the press cans so as to permit the contents ofthese cans to drop into the subjacent cans B and B.

Through the opening 22 in the pan C (see Fig. 4) passes the stem orplunger G of a press,the head G of this press being rigidly secured tothe upper end of the stem or plunger G. Preferably, the head G is formedwith a corrugated upper plate g'of a width, from front to back,corresponding to the distance between the downwardly turned flanges f ofthe diaphragm F. 'Hence, it will be seen that when either of the presscans D is shifted from the normal position shown by'full lines to thecentral position shown by dotted lines-in Fig. 2 of the drawings, notonly will the diaphragm F be moved over the head Gof the press, but theflanges f of the diaphragm will interlock with the front and rear edgesof the head G of the press, as clearly shown in Fig. 4; of the drawings.The press maybe of any suitable or convenient form. I employ ajack-press of familiar con struction. As shown, thispress comprises avertical frame H that is bolted at its bottom to the base A, andthroughthe body of this frame passes the plunger G;

The body H of the press is straddled by'a yoke Preferably,

K that is pivoted, as at 71, tothe body; H, and

to the inner'end of this yoke K is pivotally connected a link 30 thatengages at itsupper end with a cramping sleeve 31 (see Fig. 4). Throughan arm 32 projecting upwardly from the topof the body H of the press,eX;

tendsan arm 33 projecting from a cramping sleeve 34 through which theplunger G passes. Thepivoted yoke K is provided at its outer end with asocket to receive the op-- crating handle K. When the handle is forceddownward, the plunger will be raised 7 by'the shifting of thecrampingsleeve 31 through the medium of the yoke K and link 30, but the downwardmovement of the plunger will be checked as the handle K moves upward, bymeans of the sleeve 34:, in a manner well understood. When the plungerhas been moved as high as desired' and the garbage has been thoroughlycompressed, the plunger may be released and'permitted to drop downwardto its lowermost position I by raising the handleK to its highest position, at which time a shoulder k on the yoke K will engage the crampingsleeve 33 and shift this sleeve so that it will no longer cramp theplunger but will permit it'to drop.

From the foregoing description, the operation of my improved apparatus,when used fo the treatment of garbage, will be seen to be as follows:The press cans D and D will be conveniently marked to indicate thecharacter of the garbage which they are adapted to receive, and thesubjacent cans B and B may also be correspondingly marked. Into one ofthe cans D will. be

placed all garbage that is adapted for food.

purposes, such as potato or fruit parings, scraps of bread, meat or thelike, while into the other can will be placed garbage that is notadapted for that purpose, such as egg shells, coffee grounds, skins ofcitrous fruits, spoiled food, or the like, but which is adapted to becompressed. It will be understood that garbage such as bones, tin cans,or the like, will be dropped into the lower can beneath the can thatreceives the useless garbage; When a sufficient quantity has accumulatedin either of the press cans, such can will be moved from its normal.position to a central position above the head G of the press, andbeneath thecross bar 13. If desired, a thumb-screw 13 may pass throughthe cross bar 13 to bear upon the lid of the can during the operation ofthe press. When the press can has been thus brought to centralposition,the operating handle K will be reciprocated and the press head will becaused to rise and compress the garbage within the can above it. Theliquid fromthe garbage will flow down through the diaphragm F onto andaround the press head G and into the pan G, whence it will be conductedawav by the discharge pipe G After the garbage has been thoroughlycompressed (and it should remain under the press a sutlicient time topermit the liquid to escape), the head G of the press will be dropped,after which the can will be shifted laterally to normal position,carrying with it the diaphragm F. The diaphragm F may then be withdrawnfrom beneath the press can D by pulling outward the slide plate E, asthe slide plate and diaphragm are interlocked (in the manner abovedescribed) when the press can is in position above the slide plate. Asthe slide plate E and diaphragm F are thus withdrawn from the opening inthe front of the frame (J, the compressed garbage within the press canis allowed to drop into the corresponding cans B or B beneath it. Ofcourse, should the compressed garbage stick within the press can afterthe diaphragm F has been withdrawn, it may be readily forced out throughthe open bottom.

of the press can and caused to fall through the corresponding opening 20or 21 of the pan C. After the compressed garbage has thus beendischarged, the diaphragm F and slide plate E will be restored to normalposition, thereby closing the bottom of the press can and adapting it toreceive additional garbage.

By means of my improved press, not only is a convenient means alfordedfor separating. the useful from the useless garbage, but the mass ofgarbage is so reduced in volume that the expense incident to its removalis very materially lessened. So, I also, the many objections incident tothe ordinary ga rbagecans are entirely overcome.

lhe feature of employing an upwardly moving press plunger for extractingthe moisture from the garbage is an important one, as it not onlyenables the liquid to be much more readily remover. than would bepossible with a press acting upon the top of the garbage, but such apress plunger can be more col veniently disposed in a manner permittinga pluralitv of cans to be shifted over the pliiinge head.

My inve; -on will be found to possess many other advantages which willbe readily understood by those familiar with the inconvenient a dobjectionable features incident to existing methocs of garbage disposal.
